MEANS FOR SECURING METALLIC BANDS TO BOXES.

SPECIFICATION forming part of Letters Patent No. 397,262, dated February5, 1889.

Application filed July 337- To aZZ whom it may concern.-

Be it known that I, JOHN ll. \VILLIAMS, of Boston, in the county ofSuffolk and State of Massachusetts, have invented certain new and 5useful Improvements in Means for Securing Metallic Bands to Boxes,Bales, &c., oi which the following is a specification.

This invention has for its object to produce an improved means fortightening wire around and it consists in a certain improvedconstruction, WhichI will now proceed to describe, and I will point outits points of novelty in the claims at the end of this specification.

Of the accompanying drawings, forming a part of this specification,lhgurel represents a top view of myimproved band-tightenin g apparatusplaced upon a bale or package and engaged with the ends of a wire bandpreparatory to tightening and securing the latter. Fig. 2 represents asection on line m, Fig. 1. Fig. 3 represents a top view after the bandhas been tightened and its ends bent back by the reversal of theposition of the apparatus. Fig. at represents a top view showing thetightening apparatus as used to tighten a band of hoop-iron. Fig. 5represents a sect-ion on line 11 y, Fig. 4. Fig. 6 represents a sectionon line 5 5, Fig. 4-. Fig. 7 is a sectional view of a 0 modified form ofclamping device, and Fig. 8 a side view of a modified form of clampingand tightening device. Fig. 9 is a view of a modification in which oneguide-rod is employed.

The same letters of reference indicate the same parts in all of thefigures.

In carrying out my invention I provide an apparatus having two clamps, ce, each adapted to firmly grasp abin din g-wire, Z), a screw-shaft, 4o.9, having two oppositely-threaded portions, 2 2, one of which isengaged with the one clamp and the other with the other clamp, and inthe construction shown in Figs. 1., 2, 3, and -;t a suitablesupportirig-frame comprising one or more guide-rods, c, on. which theclamps are adapted to slide, and end pieces, (Z d, in which the screw isjournalcd and to which the guide-rods c are attached. Two guiderods, 0c, are here shown extending parallel with the screw 8 and affixed attheir ends to the end pieces, (I d; but it is obvious that one andsecuring it to a bale, box, or other article f Serial No. 243,229. (Nomodel.)

i of said guide-rods may be dispensed with, if desired. The screw has asuitable crank or i operating device, 5', whereby it may be rotated. Therotation of the screw causes the clamps to move simultaneously inopposite directions, 1 as will be readily seen.

The construction of the clamps may be variously modified. As shown inFigs. 1, 2, 3, 4, t and 5, each clamp is composed of a socketed 6oblock, 6, and a bolt, f, fitted in said socket and formed with atapering head, f, in one side of which is a V-shaped groove, g, Fig. 5,which receives the wire. The upper end of the bolt f is threaded andprovided with a thumbnut, h, which bears on the upper surface of theblock e. When a wire has been inserted in the groove g, the not histurned in the direction required to draw the tapering grooved headof thebolt into the socket of the block e, the wire being thus firmly grasped.

Operation: The wire band b, being passed around the bale, box, or otherarticle, with its ends overlapping, said ends are engaged with theclamps, as shown in Fig. 1. The screw is then rotated to move the clampapart, andthus tighten the band by pulling its overlapping ends inopposite directions. lVhen the desired tension has been thus applied tothe band, the operator turns the apparatus end for end, as shown in Fig.3, and by so doing beiids'back each of the overlapping ends of the wireupon itself, thus forming on each end of the wire a hook or loop, I),which is interlockedwith the hook or loop of the other end, the saidhooks or loops being of such form that they lie close to the surface ofthe bale or box and do not project therefrom, so as to be liable to becaught and displayed by external objects. The extremities of the hooksor loops may be tucked under the main portions of the wire to keep themin place, as shown. in the upper part of Fig. 1. It will be seen thatthe strain or tension is maintained on the wire by the clamps during theoperation of bending back the ends of the wire, so that there is no lossof tension or slacking of the wire during the bending operation. Theabrupt bending of the two wires into interthe tension after the clampsare removed from the wire.

locking hooks enables said hooks to maintain IOO I prefer to constructthe apparatus so that it can be used to tighten aband of hoop-iron, andto this end I provide one end of each block c with a bolt, '1', havingan offset, i, at its lower end formed to clamp a fiat band, j, betweenitself and the inner surface of the block 6, as shown in liig. As theapparatus is not to be reversed after tightening the handy, the clampsare set at a considerable distance apart before the operation, and aremoved toward each other to tighten the band. The lapping ends of theband j are formed with hooks j adapted to interlock, as shown in Fig.(5. One of the blocks 6 is made loi'iger than the other block, so thatthe ends of the band can stand side by side, as shown in Fig.- +t whilethe band is being tightened, the hooks jj being afterward movedlaterally to interlock them. The interlocked ends of the band may besecured by a staple, 71:, or other suitable fastening driven into thebox or bale, as shown in Fig. 6.

In Fig. 7 I have shown the block 6 provided with a recess, a, and agrooved clamping-jaw, 0, which is engaged with a screw-bolt, 1), wherebyit may be moved into and out of said recess to grasp or release thewire.

The construction of the clamps may be otherwise modified.

In Fig. 8 I have shown the blocks 6 6 provided with cam-shaped serratedends 6 c and with pivoted serrated levers 0 0, said serrated ends an dlevers constituting jaws which antomatically grasp the wire insertedbetween them. Fig. 8 also shows the blocks 9 e as provided with twoguide-rods, c 0, each attached rigidly to one block and adapted to slidein the other, the end pieces, (I (I, being omitted. It is obvious thatone guide-rod will suflice in the construction last described as well asthat shown in the figures previously described.

Instead of providing two gnide'rods, I may employ one, as shown in Fig.9 and heretofore described, and for some purposes this may prove thepreferred construction.

I claim 1. The combination, with the shaft having the right and lefthand screw-threads thereon, means for turning said shaft, and the twoblocks mounted 011 and adapted to be moved by said right and left handscrew-threads, whereby they are adjusted with relation to each other, ofband-clamps carried by said blocks, thumb-pieces for engaging ordisengaging said clamps with the band, and guiderods for holding theclamps in alignmen t. with each other, substantially as described.

2. The combination of the blocks 6 6, each having at one end awire-band-elamping device and at the other end a flat-l)and-clamp ingdevice, a right and left screw engaged, as described, with said blocks,and a guide rod or rods to guide the blocks in the movements imparted tothem by the screw-shaft.

3. The wire-clamp composed of a block, 6, having a socket, and a boltadapted to work in said socket and having a head or enlargementcontaining a groove formed to receive a wire band, said head arranged topass within the socket a distance sulhcient to bite and firmly hold thewire at the edge,substantially as described.

In testimony whereof I have signed my name JOHN ll. \YILLIAMS.
